This should work if the k12ltsp box is getting settings via DHCP in
both cases.  One possible problem would be if the router is
set to NAT to 192.168.0.0/24 and the k12ltsp box is also using
192.168.0.0/24 on eth0.  You can see this with:
ifconfig -a
after getting a dhcp address from the router.  The two interfaces
much have different subnet numbers.  You can change either one
but if you going to test k12ltsp and reinstall often you might
want to leave the default there and change the one on the
router.  The router should have a web interface for this and
any other number in the 3rd position (192.168.x.1 for the router,
192.168.x.0/24 - netmask 255.255.255.0 for the net) will work.
